Medical Review - Experimental/Investigational

Positional Magnetic Resonance Imaging (MRI)

DESCRIPTION
Some recent studies have suggested that imaging the body in various positions with “loading” of the spine may lead to more accurate diagnosis. This “loading” can be accomplished by having the patient stand upright or sit. Also, imaging can be completed with the patient in the position that causes the symptom(s). This is being evaluated in suspected nerve root compression and in some cases of spondylolisthesis.

A new open magnetic resonance imaging (MRI) system has been developed which allows imaging with the patient in various positions. The imaging can be conducted with partial or full weight bearing. Dynamic-kinetic imaging (images obtained during movement) can also be obtained with this system. Conventional MR imaging is completed with the patient in a recumbent position.

FONAR Corporation has 510(k) marketing clearance from the U. S. Food and Drug Administration (FDA) for a MRI system that performs positional MRI scans.

POLICY
Positional (non-recumbent) magnetic resonance imaging (MRI) is considered experimental/investigational including its use in the evaluation of patients with cervical, thoracic, or lumbosacral back pain.  

CPT Code
Currently, there is no way to signify with coding that an MRI is open or positional. The service would be coded using the CPT code for the MRI scan.
